Back in March, Wyatt Jackson, a Boston-based entrepreneur and hip-hop artist, wrote and performed a rap song about A Whole New Mind. Now he has another project, this one far more worthy. He and three other Boston rappers have formed 4Peace, a group that advocates against violence using the power of hip-hop. You can read more about the venture in this Boston Globe story (free subscription required). You can watch the video of their song, “Start Peace” here.
